Modelling and Simulation of AdHoc Network Traffic Based on Tactical Communication Environment

Tactical communication network environment is different to the civil mobile adhoc network. It is of special connectivity, traffic flow characteristic and mobility. Its traffic flow model is the foundation for adhoc network designing, planning, controlling and managing. Each characteristic can be depicted correctly only when the model is accuracy. This thesis studied the traffic flow characteristics of the tactic adhoc network and putting forward an implementation method of creating traffic flow model. To solve the problem of loading traffic distribution model, it provides an address generating model using improved OPNET PDF probability editor named “PDF Destination Address model” which can send packets in accordance with traffic flow distribution proportionate relations matrix between each units. It can achieve traffic flow more quickly and effectively. Simulation experiment is operation in different parameters conditions and the results demonstrate that the proposed model of generating traffic flow between each units is effective. This method which can meet each unit’s requirements of traffic flow size, intensity and orientation can be effectively applied in tactical adhoc communication network simulation and performance research.
